OIL-CUP.

.SPECIFICATION forming part of Letters Patent No. 392,161, dated October 30, 1888.

'Application moa .rune 5,1sss. serial No. mausi. (No mmm To' @ZZ whom it may concern.-

Be' it known that we, WILLIAM F. Mk'rfrns and JoH'N F. LEwIs, citizens of the United States, residing at Scranton, in the county of Lackawanna andvState of Pennsylvania, have invented certain new and useful Improvements in-Oil-Cups; and we do declare the following to` be a full, clear,and exact description of the invention, such as will enableY others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and gures of reference marked thereon, which form a part of this specication.

This invention relates to lubricators which bodying my invention; Fig. 2, a vertical section of the lubrieator on the'lline Y Y of Fig. 11.5' and Fig. 3, va cross-section on the'line X of Fig. 2, looking down.

C is `the body of the cup or receptacle for grease.

.B isa base having a shank, H, by which it is`secured to the part to be lubricated.

H2 is a hole through the shank, and R is a screw-plug, by means of which the hole I-l2 may -be more or less closed.

P is a pistou working in the interior of the cup C and having a rod or tube, G, fastened to it.

- C2 is acylindrical projection of the cup C.

F and F2 are interior anges ofthe cylind rical projection C2, andare notched at N and N 2.

T is a hollow handle orplunger which passes through the flanges F and F2, and has the upper end closed by the cap T.

S is a spring in compression when the cup is filled, and therefore tends to force the hollow handle T upward out of the tubular projection G2, but is prevented from so doing by the cap T2 coming in contact with the stop G2, the latter being fastened tothe rod G.

I)2 are stubs fastened to the hollow handle T.

The screw-plug R has a hole, R2, through it, or a notch may be cut in theedge of either the plug or the hole that it screws into. The plug is also slotted for a screw-driver.

Vhen thehandle T is pushed down until one or more ofthe stubs D2 have passed through 6o the notch N, and is then turned around until the stub has caught underneath the flange F,

the power of the spring S will be exerted to press the pistoni? downward; but as this ac! tion is resisted bythe grease in the cup G it can 6 5 take place but slowly--to wit,as rapidly as the grease is expelled through Vthe opening H2- and in the meantime the rod G, projecting above the cap T, serves to indicate how mu'ch grease has yet to be expelled before the opera- 7o tion will be arrested by the cap Gr2 corningin contact with the cap T". I f the handle T has been pressed down until the uppermost of the stubs DY2 has been caught underneath the flange F, then when the rod Gdescends untilthe cap G2' strikes it VVwill indicate that the cup has been entirely emptied of grease. The two I'ianges F and F act in conjunction to Aguide the handle T. The notches N and N2 are best in the vertical plane, and it is immaterial to the working whether when the handle T is Ypressed down the stubs D2 catchbeneath F orV F2. The rod Gr, which may be either solid or hollow, being' guided near its upper end by the cap T2, serves in turn to guide the piston l? 85 and is useful for pulling the piston back when the cap is to be rellec Ha'vingthusvdescribed our invention, what we claim, and desire to secure by Letters P atent, is '-f 1. Alubricating device having in combination acup with a springactuated piston working therein, said cup having a feed-hole in its bottom and a cylindrical projection upon the top of the same, a hollow handle arranged to 95 slide within the said projection, and a spring inclosed within the handle.

2. A lubrieator consisting of acup having a feed-hole, an apertured screw-plug in its bottom, anda cylindrical projection, a hollow handle having cap T2 at its top, apiston working within the cup, a piston-rod fastened to 5 the piston and passing through the handle, a

stop fastened to the rod, and a spring surrounding said rod.

8. A lubricating device having a cup with a feed-hole in its bottoni,a1id a cylindrical pro- Io'jection with an inner iiange, piston P, rod G,

stop G2, handle T, with cap T2 and spring S.

4. The combination, with the cup having a feed-hole in its bottoni, and the cylindrical projection having an inner flange whieh'is 15 notched, of the piston, the hollow handle having one or more stubs, and the spring interposed between the piston and the hollow handie, substantially as described.

5. The combination, with the cup provided 2o with a feed-hole in its bottom,and with a cylin- WILLIAM F. MATTES. JOHN F. LE\VIS.
